Preparation of Primary Explosive by Self-assembly of Combustible and Oxidizing Agents under Acid.

In order to further explore the effect of ligands on the performance of primary explosives and gain a deeper understanding of the coordination mechanism, we designed furan-2-carbohydrazide (FRCA), a ligand, by using oxygen-containing heterocycles and carbohydrazide. Then, FRCA and Cu(ClO) were used to synthesize coordination compounds [Cu(FRCA)(HO)(ClO)]·CHOH () and Cu(FRCA)(HO)(ClO) (). The structure of the was confirmed by single-crystal X-ray diffraction, IR and EA characterization. Further experiments on show that has good thermal stability, but is sensitive to mechanical stimuli (impact sensitivity = IS = 8 J, friction sensitivity = FS = 20 N). The predicted value of the detonation parameter is = 6.6 km s, = 18.8 GPa, but the ignition test, laser test, and lead plate detonation experiment show that has excellent detonation performance, which is very worthy of attention.
